Sneaky Machines

The hidden tricks inside everyday things.

Why your helmet only works once. Why your bike's brakes let go on purpose. Why a foldable phone's screen creases. Sneaky Machines opens up the machines you use every day and shows the hidden mechanism inside, in short 3D animations.

Original 3D X-rays · every fact sourced. Every Short is made in Blender and checked against primary sources (manufacturer manuals, standards, regulators), which are linked in each video description. The visuals are illustrations; anything exaggerated is labelled on screen.

New Short every 2 days. Spotted a mistake? Tell us in the comments: corrections are welcome.
